Before Ordering
〇 Regarding Import Consumption Tax
At Shaft-ya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges other than the total amount paid at checkout.
〇Confirmation of Compatibility
As our entire product database is based on North American vehicles (USDM), please confirm whether or not they can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so if you have any questions, please contact us before ordering.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually by email.
Essentially, all products are shipped internationally from our warehouse in the United States. Unlike domestic shipping within Japan, international shipping takes about 7 to 14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air. They will not be shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially, all products we handle are designed and manufactured outside of Japan. Please note that they do not conform to the "Japanese Vehicle Inspection System," and we cannot provide strength evaluation documents or similar for that purpose. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packing box or the product. We will only handle returns, refunds, or replacements for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please understand this policy. Furthermore, regarding products sold through our company, all warranty-related support will be handled "exclusively through our company." Please note that we do not handle support through other companies or distributors located within Japan.
